Analyze
LCP: O PROTREJ [Open] id 9 len 46 protocol IPCP indicates that the Protocol
is rejected and this seems to be happening due to a mis-configuration.
I don’t see a dialer interface configured.
Please modify your config and make it as it is mentioned below:
interface Group-Async1 no ip address encapsulation ppp dialer in-band <!-- Add this line--!> dialer-group 1 <!-- Add this line--!> !---apply interesting traffic definition from dialer-list 1 async dynamic address async mode dedicated peer default ip address pool dialin_pool ppp authentication pap chap callin <!-- Add this line--!> group-range 0/386 0/421 ! dialer-list 1 protocol ip permit <!-- Add this line--!> !--- All IP traffic is defined interesting. !--- This is applied to Group-Async1 using dialer-group 1
Resolved
After add top config, the problem resolved.

dialer in-band:
———————-
The dialer in-band command specifies that chat scripts will be used on asynchronous interfaces and V.25bis will be used on synchronous interfaces. The parity keywords do not apply to asynchronous interfaces. The parity setting applies to the dialer string that is sent out to the modem. If you do not specify a parity, or if you specify no parity, no parity is applied to the output number. If odd parity is configured, the dialed number will have odd parity (7-bit ASCII characters with the eighth bit as the parity bit.) If an interface only accepts calls and does not place calls, the dialer in-band interface configuration command is the only command needed to configure it. If an interface is configured in this manner, with no dialer rotary groups, the idle timer never disconnects the line. It is up to the remote end (the end that placed the call) to disconnect the line based on idle time.
You can config “dialer in-band” under multi BRI/PRI port or direct config under dialer port , and use “dialer pool-member 1” bundle to virtual dialer port.
